Final answer:
To find the weight of the wooden cube, you multiply the pressure it exerts (1200 Pa) by the area of the side in contact with the surface (2.25 m^2), which results in 2700 N.
Step-by-step explanation:
The student asks about finding the weight of a wooden cube given its dimensions and the pressure it exerts. To calculate the weight (F), we use the formula Pressure (P) = Force (F) / Area (A). Given Pressure (P) is 1200 Pa and the cube's dimensions (1.5m x 1.5m), we find the area of the side of the cube that is in contact with the surface, which is 1.5m × 1.5m = 2.25m². The weight of the cube (F) is then found by rearranging the equation to F = P × A, which gives us F = 1200 Pa × 2.25m² = 2700 N (newtons).
